If Ra-226 had a f life of 1600 years and you have 20 grams how much will be left in 3200 years?
After 1600 years, half of the 20 grams of Ra-226 will remain, so 10 grams will be left. After another 1600 years (3200 years total), half of the remaining 10 grams will remain, resulting in 5 grams of Ra-226 left.
Why is a loss or gain in mass of less than 0.01 grams considered to be insignificant change in mass?
That depends on the scale you're working in. If you are working with kilo grams the change is insignificant, but if you're working with 1,00 grams the change is significant.
In a chemical reaction the total mass of the reactants is 10.0 grams The total mass of the products must be?
The total mass of the products will also be 10.0 grams according to the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
How do you change grams to mas?
Grams already is a unit of mass. If you want to convert to kilogram, divide by 1000.
What is the mass of 60 grams 0 grams and 2.2 grams?
The mass of 60 grams is 60 grams, the mass of 0 grams is 0 grams, and the mass of 2.2 grams is 2.2 grams.
How many grams are there in 3.2 kilograms?
There are 3200 grams in 3.2 kilograms. This conversion is based on the fact that there are 1000 grams in 1 kilogram. Therefore, to convert kilograms to grams, you multiply the number of kilograms by 1000. In this case, 3.2 kilograms x 1000 = 3200 grams.
What is the mass of ml?
The estimated mass of 300 ml is about 300 grams. This can change based on the temperature and the density of the sample.
a caterpillar eats 1400% of its birth mass in one day. the caterpillars birth mass is m grams. which of the following expressions could represent the amount in grams the caterpillar eats in one day?
B,A
If the mass of the container is 14.5 grams what is the mass of the sand?
To determine the mass of the sand, you'll need to subtract the mass of the container (14.5 grams) from the total mass of the container with sand in it. For example, if the total mass of the container with sand is 50 grams, then the mass of the sand would be 50 grams - 14.5 grams = 35.5 grams.
What is the mass of the powder if the combined mass of the powder and its container is 12 grams and the mass of the container alone is 4 grams?
The mass of the powder is 8 grams. This can be calculated by subtracting the mass of the container (4 grams) from the combined mass of the powder and container (12 grams), leaving the mass of the powder as 8 grams.
If you start a chemical reaction with 20 g of reactants the mass of the products produced will be how many grams?
Following the Law of Conservation of Mass (see link below), there will be 20 grams of products in a reaction of 20 grams of reactions.
How many grams are in mass?
Grams are a measure of mass.
